Question

使用带参数的存储过程显示我的视图时出现了一点问题。

这是我的代码：

查看

@model IEnumerable<PEMCOLoan.DAL.Entities.spModels.getLoanWithTypes>

@{ 
    ViewBag.Title = "List of Summary per Loan Types";

我想要的是，我想检查一下它与桌子相处的贷款类型。例如，如果我有贷款类型1,2,3，如果贷款类型1将与Educational Loan的记录一起，2将与小额现金等等...这里是我的图片从事。其他小组的情况也是如此。

控制器

现在我暂时有这个

        [HttpGet]
    public IActionResult Index()
    {
        return View(_Context.Set<getLoanWithTypes>().FromSql("sp_GetLoanTypesWithPrincipal").AsNoTracking());
    }

以下是我的带参数的部分代码

        [HttpGet]
    public IActionResult Index(getLoanWithTypes glwt)
    {



        return View(_Context.Set<getLoanWithTypes>().FromSql("sp_GetLoanTypesWithPrincipal @p0 = {0}, @p1 = {1}", glwt.EmployeeID.ToString(), glwt.LoanTypeID.ToString()).AsNoTracking());
    }

我有一点问题，因为我不知道如何从视图中传递参数。我想要做的是我想在视图加载时为每个LoanTypeID设置参数。或者只需单击每个面板，它就会设置LoanTypeID参数。

SQL： 参数：的 @empID AS INT = NULL， @loanID AS INT = NULL

查询：

SELECT
[EmployeeID] = emp.EmployeeID,
[FullName] = emp.FName + ' ' + emp.LName,
[LoanTypeID] = lt.LoanTypeID,
[PrincipalAmount] = (SELECT ISNULL(SUM((CAST(((lc.LoanAmount) / ((dbo.fnNumberOfYears(CONVERT(VARCHAR(15), LoanDateStart, 101), CONVERT(VARCHAR(15), LoanPaymentDue, 101)) * 12)  * 2)) AS DECIMAL(18,2)))),0) FROM LoanContract lc INNER JOIN LoanType lt ON lt.LoanTypeID = lc.LoanTypeID WHERE lc.LoanTypeID = @loanID AND lc.EmployeeID = emp.EmployeeID),
[Interest] = (SELECT ISNULL(SUM((CAST((((lt.InterestRate/100) * lc.LoanAmount) / ((dbo.fnNumberOfYears(CONVERT(VARCHAR(15), LoanDateStart, 101), CONVERT(VARCHAR(15), LoanPaymentDue, 101)) * 12)  * 2)) AS DECIMAL(18,2)))),0) FROM LoanContract lc INNER JOIN LoanType lt ON lt.LoanTypeID = lc.LoanTypeID WHERE lc.LoanTypeID = @loanID AND lc.EmployeeID = emp.EmployeeID),
[Total] = (SELECT ISNULL(SUM((CAST(((((lt.InterestRate/100) * lc.LoanAmount) + lc.LoanAmount) / ((dbo.fnNumberOfYears(CONVERT(VARCHAR(15), LoanDateStart, 101), CONVERT(VARCHAR(15), LoanPaymentDue, 101)) * 12)  * 2)) AS DECIMAL(18,2)))),0) FROM LoanContract lc INNER JOIN LoanType lt ON lt.LoanTypeID = lc.LoanTypeID WHERE lc.LoanTypeID = @loanID AND lc.EmployeeID = emp.EmployeeID)
FROM Employee emp
    INNER JOIN Salary sal ON sal.EmployeeID = emp.EmployeeID
    INNER JOIN LoanContract lc ON lc.EmployeeID = emp.EmployeeID
    INNER JOIN LoanType lt ON lt.LoanTypeID = lc.LoanTypeID
    LEFT JOIN LoanPayments lp ON lp.LoanID = lc.LoanID
    LEFT JOIN LoanFrequency lf ON lf.LoanFrequencyID = lc.LoanFrequencyID
WHERE emp.EmployeeID IN (SELECT EmployeeID FROM Employee WHERE EmployeeID LIKE '%' + CASE WHEN ISNULL(@empID,0) <> 0 THEN CAST(ISNULL(@empID, 0) AS VARCHAR(15)) ELSE '' END + '%')
    AND lc.LoanTypeID IN (SELECT LoanTypeID FROM LoanType WHERE LoanTypeID LIKE '%' + CASE WHEN ISNULL(@loanID,0) <> 0 THEN CAST(ISNULL(@loanID, 0) AS VARCHAR(15)) ELSE '' END + '%')
GROUP BY emp.EmployeeID, lt.LoanTypeID, emp.FName, emp.LName
ORDER BY emp.EmployeeID ASC

它的作用是每个员工获得当前的PrincipalAmount，Interest等等......如果PrincipalAmount具有相同的LoanTypeID和EmployeeID，那么它将计算和总和。以下是示例图片

我对asp.net核心和ef核心有点新意，还没有先进的知识。

希望这足以满足一切。任何好的参考阅读或建议将不胜感激！谢谢！

Answer 1

您可以构建__init__()并将其作为参数值提供。这允许您在SQL查询字符串中使用命名参数

Counter

框架将匹配参数直到命令。

参考 - Adding a single character to add keys in Counter

使用参数
